Using the Centillion EtherSpeedII Switch Modules

Desktop Switch with ATM Uplinks

In the example shown in Figure 2-4, the EtherSpeedII 10/100BASE-T switch module provides 20 RJ-45 switched Ethernet (10/100 Mb/s) ports to connect to desktops, with redundant high-speed ATM OC-3c and OC-12c ports to connect to an ATM backbone. This network configuration can support small to large wiring closets.

Figure 2-4 also illustrates a sample network providing ATM uplinks to a Centillion 50/100 chassis. Servers are connected to the network through the Centillion 50/100 chassis, and network stations are connected to the 10/100BASE-T ports on the EtherSpeedII 10/100BASE-T switch modules. The chassis are dual-homed with ATM OC-3c and OC-12c uplinks to the Centillion 50/100 chassis and the Model 5000/5005BH chassis. These chassis can be interconnected with multiple ATM links.
